Hardened steel bushings are bushings obtained through a hardening process, which involves heating the steel to a high temperature and then rapidly cooling it. This process, known as quenching, increases the hardness and strength of the steel, making it more resistant to wear and deformation. The hardened steel is then tempered, which involves reheating it to a moderate temperature and then cooling it again. This reduces brittleness while maintaining the increased hardness, significantly enhancing the hardness and durability of the bushings, making them ideal for heavy-duty applications.

Instead, case hardened steel bushings are made from steel that has undergone a carburizing treatment, which involves the addition of carbon to the surface layer. This creates a hard outer shell while retaining a softer, more ductile core. The carburizing treatment increases the surface hardness and wear resistance of the bushings, making them suitable for applications where surface durability is crucial.

Types of Hardened steel Bushings

• Sleeve
• Grooved
• Collar
• Oversized
• Custom

Application

Hardened steel bushings are essential in various types of applications, particularly where significant stresses and heavy loads are involved. They are commonly used in the following sectors:

Bushing Tolerance

Tolerance in engineering is the allowable variation in a physical dimension or measured value. It’s crucial for ensuring parts fit and function properly.

For a Sibo Bushing, the standard tolerances are:

• u6 for the outer diameter,
• C8 for the inner diameter.

These tolerances ensure, according to ISO standards, the correct press fit in a housing hole with H7 or H8 tolerance, and the proper clearance with a shaft with h7 tolerance.

Lubrication 

Lubrication is essential for the proper functioning and longevity of bushings. It reduces friction and wear, prevents corrosion, and helps to dissipate heat. Here’s a brief overview of the lubrication process for bushings:

Types of Lubrication

• Grease: A common lubricant for bushings, providing a thick layer that stays in place and offers good protection against contaminants.
• Oil: Offers lower friction than grease and can be used in systems with continuous lubrication, such as oil baths or circulating systems.
• Solid Lubricants: Such as graphite or PTFE, can be embedded in the bushing material for maintenance-free operation.

Bearings are mechanical components designed to facilitate movement by reducing friction between surfaces. There are several types of bearings, including sleeve bearings, ball bearings, rolling bearings, and sliding bearings.

Sleeve bearings, also known as plain bearings, are cylindrical and smooth, resembling the shape of a sleeve. They are sometimes referred to as sliding bearings because they enable sliding motion. In some contexts, the terms bushing or sleeve bushing are also used to refer to the same component.

The key difference between sleeve bearings and ball bearings lies in their construction and function. While ball bearings use rolling elements to reduce friction, sleeve bearings rely on a smooth surface to allow for sliding motion.

Materials

Sleeve bearings can be made from a variety of materials, such as hardened steel, stainless steel, syntenthic, brass, and bronze. The material choice depends on the specific application, environment, and load requirements. Each material offers its unique benefits:

Hardened Steel

Hardened steel sleeve bearings are made by heating steel to high temperatures and rapidly cooling it, a process called quenching. This increases hardness and wear resistance, making them ideal for high-load applications. Additionally, case-hardened options feature a carburized surface that enhances durability while maintaining a softer core, suitable for applications requiring strong surface performance.

Stainless Steel

Offers superior corrosion resistance, making it ideal for use in corrosive environments, such as those with high salinity or exposure to chemicals.

Synthetic Materials

Lightweight, corrosion-resistant, and suitable for applications with lower loads. This category includes plastics and other engineered materials designed for specific performance requirements.

Brass/Bronze

Provides self-lubrication properties and high durability under moderate loads.

Types of Sleeve Bearings

There are several types of sleeve bearings designed to meet specific needs. These include plain sleeve bearings, flanged sleeve bearings, grooved sleeve bearings, and split sleeve bearings.

Plain Sleeve Bearings

Plain sleeve bearings are the simplest form of sleeve bearings, featuring a smooth cylindrical shape. These bearings are used in a wide range of applications where low friction and ease of movement are essential. The simplicity of design makes them cost-effective and versatile for various machinery.

Flanged Sleeve Bearings

Flanged sleeve bearings have a flange at one or both ends of the bearing, which helps keep the bearing in place. This added flange allows for easy installation in housings without requiring additional components like retaining rings. They are ideal for applications where axial alignment is crucial, such as in motors or pumps.

Grooved Sleeve Bearings

Grooved sleeve bearings feature grooves along the surface of the bearing, which help with lubrication distribution and reduce friction. These grooves help maintain an even layer of lubricant between the bearing and shaft, improving efficiency and lifespan, especially in applications with high-speed movement or heavy loads.

Split Sleeve Bearings

Split sleeve bearings are divided into two halves, which can be easily installed or removed without disassembling the equipment. This feature is particularly beneficial for applications where maintenance is frequent or where space is limited. They are commonly used in larger machinery or engines, where ease of installation and replacement is critical.

Applications

Sleeve bearings are widely used across various industries due to their versatility and efficiency. They can be used in a wide range of applications, including:

• Machinery: Ensure low friction and reliable motion in industrial machines.
• Construction Equipment: Used in lifting equipment, cylindrical hydraulic systems, and other heavy-duty machinery for durability and efficiency.
• Agricultural Equipment: Reduce wear and enhance the longevity of farming machinery, even in demanding environments.
• Automotive Components: Integral to engines, transmissions, and other systems requiring smooth operation.

Sleeve bearings vs ball Bearings

Sleeve bearings are typically used for low-speed applications and provide a smooth sliding motion, relying on a lubricant to reduce friction. Ball bearings, on the other hand, are ideal for higher speeds and loads, as they use rolling elements to minimize friction and handle radial and axial forces efficiently.

Bush replacement is a crucial step in maintaining the proper functioning of earth-moving machines, such as excavators, backhoes, drills, and lifters. There are various methods for installing a bush, each with its own advantages and disadvantages. Let’s examine the most common methods. Here you can find our tutorial video on YouTube.

Bushing press fit: Hydraulic Press  

This method uses the force of a hydraulic press to insert the bush into its seat. It’s crucial that the press is correctly aligned with the bush and seat. Misalignment can cause damage to the bush or the seat. Moreover, the applied pressure must be adequate for the task. Excessive pressure can cause ovalization and deformation, while insufficient pressure might not allow for correct installation.

Mounting Bushings Without a Press: The Liquid Nitrogen Method

The liquid nitrogen assembly method takes advantage of thermal contraction. The bush is cooled with liquid nitrogen, causing it to shrink. Once cooled, the bush is inserted into its seat. As the bush warms up, it expands, ensuring a perfect fit. It’s important to remember that liquid nitrogen must be handled with care and can cause severe cold burns if it comes into contact with the skin. Therefore, it’s essential to wear gloves and protective glasses when handling this liquid. Also, once the bush has been cooled, it should be installed as quickly as possible. If the bush is allowed to warm up before installation, it may not fit properly. Finally, after installation, the bush should be left to warm up evenly at room temperature.

Bushing press fit: Hammer

Although this is the simplest method, it’s also the least recommended, in fact, we strongly advise against it. Using a hammer to install the bush can easily lead to deformations of both the bush and the seat. This method should be avoided if possible, as it’s imprecise and overly approximate.

Let’s explore a concise overview of some of the top mining exhibitions and conferences worldwide. These events serve as crucial platforms for industry professionals, showcasing cutting–edge machinery, equipment, and technologies related to electronic control devices, robotics, and more.
